[QUOTE="FEENIX, post: 731078, member: 14204"] Good on you! That .270 will make one happy young shooter/hunter. I'm in no means an expert on the AI as this my first wildcat/AI. The. 270 Win has a shoulder angle of 17 deg 30' and the. 270 AI has 40 deg. Essentially, the AI case once fire-formed will have dimensions that are straigther in the body with less taper. This increases capacity (~6 grains) for more powder and increased velocity. The sharper AI shoulder angle contributes to more consistent headspace and less case stretching. It is also believed to improve barrel life by reducing throat erosion. Hopefully, others with more knowledge and experience will chime in. [/QUOTE]
